Police have today confirmed tragic children's TV presenter Mark Speight was found hanged on the roof of a building next to Paddington railway station in west London.

A spokeswoman said the 42-year-old's body was found by rail staff at 10am on Sunday "in a remote area out of public view".

She added: "The body was removed from the scene and taken to Westminster Mortuary.

"A post-mortem is expected (soon) when formal identification will be made.

"A report is being prepared for the coroner and investigations are continuing."

Mark had gone missing six days earlier and questions are being asked about the length of time it took to find him.

The 42-year-old was in turmoil over fiancee Natasha Collins who died in a scalding bath after a drugs binge.

As tributes poured in for Mark, his lawyer Nabeel Sheikh said: "He had real difficulties in coping with what happened to Natasha and as a result has taken his life.

"It was too much for him. I didn't think he was dealing with it well, that's been borne out by what has happened. It's an absolute tragedy. The loss of another young person's life.

"His fiancee's family have been through hell and now his own family are too."

Mark's distraught mum Jackie said at the family's home in Wolverhampton: "This is a very difficult time for us.

"We are all extremely upset. The news is absolutely devastating."

Mark, star of CBBC show Smart, was found just hours after his dad Oliver made an emotional appeal for his son to get in touch.

After being told of his son's death he said: "Mark was a wonderful son and brother and he will be very sadly missed."

Police believe Mark died the day he went missing. His body was discovered two days after best friend Stu Goldsmith told how he feared he was on the verge of a breakdown.

Mark vanished five days after 31-year-old Natasha's inquest heard she snorted cocaine and downed wine and vodka before she died at their flat in St John's Wood, North London.

He had been staying with his fiancee's mum Carmen since her death.

Mark's friend Stu believes police should have done more to find his friend. He added: "They knew there was this man out there who was in a fragile state of mind and they took six days to find him. They should have doubled their efforts.

"I'm devastated. He was my best mate. There were always two sides to Mark, the warm, funny guy which on TV and the sensitive guy which only his close friends knew about.

"I know Mark blamed himself for Natasha's death and it affected him considerably."

Mark's agent Jan Kennedy added: "Mark was truly gifted. He was blessed with a remarkable personality, great artistic talents and the wonderful ability to communicate those skills with people, especially children."

The BBC said: "Mark was a hugely talented and very popular presenter for many years."

In his last interview, Mark told how life "will never be the same without Natasha". He added: A part of me died with her."
